Abstract

With the increasing use of equipment that demand electric drive systems, the need for new systems that meet requirements of compactness, versatility, safety and low cost has increased. The IRAM module is an electronic circuit that provides a driver for DC and AC motors, being extremely compact and presents high performance. In this context, this work contributes to the power electronics area, presenting a design and construction of a low cost drive system, based on IRAM module, developed for individual or simultaneous drive, up to two DC motors. To carry out the experiments, DC motors responsible for moving a welding robot, were used. Experimental results are presented to shown the feasibility of using this system.

Highlights

The task of power electronics is to process and control the flow of electrical energy, supplying voltages and currents appropriately for load (MOHAN; UNDELAND; ROBBINS, 2003)
Due to the high use of technological equipment that require electric drive, highly effective drive systems are required, which meet safety issues, in addition to being compact and versatile units. They enable the application of electric machines in the most diverse equipment and robots, meeting the requirements of their loads
The IRAMS10UP60A module is an integrated circuit developed by manufacturer International Rectifier

Summary

Introduction

The task of power electronics is to process and control the flow of electrical energy, supplying voltages and currents appropriately for load (MOHAN; UNDELAND; ROBBINS, 2003). The IRAM module, was designed to improve the application of motors drive and speed control (INFINEON TECHNOLOGIES AUSTRIA AG, 2017) This module is a hybrid integrated circuit that provides a high performance driver for DC or AC motors, acting in the motor power stage development. The IRAMS10UP60A module is an integrated circuit developed by manufacturer International Rectifier This module, treated as IRAM throughout this work, is used for electronic control of motors, and can be applied in washing machines, refrigerators, among other machines (INTERNATIONAL RECTIFIER, 2012). The drive circuit half-bridge allows the load to be supplied with up to half applied voltage (positive and negative) It has only one inverter arm, composed of a pair of switches, connected in anti-parallel with diodes, which operate in a complementary way. DC bus power input, up to 600 V (IRAM limit), but limited to 40 V by DC-DC regulator
